To measure the primary winding resistance:
-Set the ohmmeter to the x 1 n range, and connect one
ohmmeter lead to the pink lead and the other to the
green, black, or blue lead from the ignition coils.
To measure the secondary winding resistance:
-Unscrew the spark plug caps from the spark plug leads.
-Set the ohmmeter to th
x 1 kn range, and connect
